TO ALL WHOM IT MAY CONOERN:

13e it known that I, ALFRED M. SEABURY, ot' Johnstown, in the county of Fulton, and State of New York, have invented, made, and applied to use, a certain new and useful Improvement in Cross-Cut Saws; and I dov hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 1 is aside view of said saw. Figure 2 shows a. portion ofthe saw edgewise ofthe same and Figure 3v shows a portion ofthe edge of the saw in larger size.

Cross-cut saws have heretofore been made with pairs of diamond or scoring-teeth, and pairs of chisel or clearing-teeth, so that said saws cut in both directions, and are adapted to use with two handles, one at cach end. Teeth of this character are xnot adapted to the ordinary carponters cross-cut saw, or to use in a buck-saw. The nature of' my said invention consists in a hand-saw for cutting in one direction'7 in which groups of diamond or scoring-teeth are combined with groups of chisel-teeth, similar to the teeth of a, rip-saw, the groups being separated by notches running into the-blade of the saw, soos to form receptacles for the dust in tho korf. l In the drawing, a represents the saw-blade, of any desired size or shape; 6 is the handle. The groups of diamond-pointed teeth, set or spread as usual, are shown at c c, and the groups of chisel or clearing-teeth are shown at d d. e e are notches, cut into the saw-blade, between the respective groups of teeth. These notches form receptacles for the sawidns't while being conveyed out of the kerf.

A saw formed in the manner aforesaid will cut much more rapidly and with less labor than the ordinary cross-cut saw, and is adapted only to use as a carpenters or buck-saw that ents in one direction.

. What I claim, and desire to secure by Letters Patent, is y A eross-cut saw, formed with groups of diamond or scoring-teeth e c, and chisel-teeth d d, standing in one direction, and with notches between said groups of teeth, as and for the purposes specified.

In witness whereof I have hereunto set my signature this thirty-first day of October, A. D. 1866. ALFRED M. SEABURY.
